Why hackers can access database from big companies but can't access Google's search algorithm? | [
"Are you so certain that people have not hacked or have access to these materials? I'm not so certain. Hackers don't announce their hacks 999/1000 times. They don't make it public. Why would they? That just means people will know they got hacked, fix the problem, and try to find the hacker. Or the hacker could jus... | [

Why does each piece of a broken mirror have its own reflection | [
"When you break a mirror, you multiple smaller mirrors. Unless those mirrors are oriented in exactly the same way, the light will bounce off of them at a different angle and give you a different mirrored image. If they *are* oriented the the same way, they will still reflect the same angle back at you."

With today's modern audio technology, such as ISDN, why is the sound quality still so poor in phone conversations? | [

"Radio is generally a wideband audio signal, 8-20khz, phones are traditionally around 4khz pf audio bandwidth, when someone calls into a radio show you can hear the contrast between the 8-20khz wide audio the radio has, to the 4khz wide audio a phone call has - the effect is much more obvious on FM than on AM radio... | eli5_question_answer | {

why do people get so passionate about their sport's team when they are technically not affiliated with them? | [
"from what I've seen, a lot of people think of their sports team as direct representation of the region they live in/are from, and are trained to see it that way since childhood (if their family are also big into the team). you see this a lot with teams based in smaller cities, like the Green Bay packers, because a... | [

Why can't we attach a 100X microscope to the eye piece of a 100X telescope and get a 10000X zoom? | [
"It's really hard to answer this in an ELI5 manner, there's a lot of complex optical physics in play. What is important in optical systems, particularly when you are talking about 'zoom' is resolution. By resolution, I don't mean how many pixels are on your screen, or how many megapixels the camera has. It is, the... | [
"> My simple logic would think that making the DSLR lens would be comparatively cheaper because you would not be working with miniature lens and components which will give you more flexibility in design and selecting components.

Why do all the planets in our Solar System orbit the sun in a latitudinal path/on the same plane? | [
"A nebula ie a cloud of gas starts to collapse. The conservation of angular momentum result in that is spins. If you have a spinning cloud with particles that travel in random direction they start to collide. A spinning direction will be dominant and a disc start to form Particles that have a another orbit then th... | [
"The earth rotates in a plane around the sun. The rotation of the Earth along its axis doesn't match this plane. Therefore the Earth is tilted on its axis.

Why can't a brute force attack break cryptography key? | [

How do those bladeless fans work? | [

Why is it that my PC can run high-end games easily, but is unable to emulate Nintendo DS games smoothly? | [

Why does fusion release energy? | [

Why did the automotive industry choose 12v systems over other voltages? | [
